气溶胶喷雾对空气和物体表面的消毒效果

Aerosol Spray Disinfection to the Air and Surface in the Wards

目的 测试气溶胶喷雾过氧乙酸、过氧化氢 (H2 O2 )对医院病房、救护车内空气和表面消毒效果。方法 按“消毒技术规范”规定方法进行。结果 对白色葡萄球菌 (即金黄色葡萄球菌 ) :过氧乙酸和 H2 O2 0 .0 5 %～ 0 .15 %2 0～ 3 0 m l/ m3,作用 5～ 3 0 min,杀灭率为 99.99% ;对细菌芽胞 :过氧乙酸 0 .1%～ 0 .8% 2 0～ 3 0 ml/ m3,作用 3 0～ 60 min,杀灭率为 99.99% ;对自然菌 :过氧乙酸 0 .6% 2 0 ml/ m3,作用 60 min,平均杀灭率为 99.48%。结论 用气溶胶喷雾过氧乙酸对医院病房、救护车内空气和表面进行消毒处理 :0 .1%～ 0 .8% ,2 0～ 3 0 ml/ m3,作用 3 0～60 min,均达到可靠的消毒效果 ;此方法使表面消毒和空气消毒相结合 ,较传统的甲醛熏蒸消毒效果好、毒性低、省药、省时、方便。

OBJECTIVE To examine aerosol spray disinfection effect by using peracetic acid and H 2O 2 to the surface and air in the wards and ambulances. METHODS The methods used were in accordance with Disinfection Technology Criteria.RESULTS The Staphylococcas aureus is killed 99.99% by using 0.05 0.15% per acetic acid and H 2O 2 20 30 ml/m 3 for 5 30 minutes, the bacterial spores were killed 99.99% by using 0.1～0.8% per acetic acid 20 30 ml/m 3 for 30 60 minutes, the natural microbes were killed 99.48% by using 0.6% H 2O 2 20 ml/m 3 for 60 minutes.CONCLUSIONS The disinfection effect is credible to spray the air in the wards and ambulances,by using 0.1 0.8% per acetic acid 20 30 ml/m 3. The surface and air disinfection in combination is better than formaldehyde fumigation in favor of low toxicity,less drugs and times and more convenience and easiness.
